IMFRQVED BAMBI-STRAP.

TO ALI.. WHOM IT MAY CONCERN:

Be it known that I, MARTN '.l. Barcos, of Sohoolerait,AV in; the county of 'Kalaniizoa and in the State ,of Michigan, have invented ny new und usei'ul Improvement in Hume-Straps; and do hereby declare the following to ne a full, clear, and exact description et' the same, reference being' had to the accompanying drawings, in

Figure I is an enlarged View of my llame-fastening detached. Figure 2 shows the same in operation. I Figure 3 is a section taken on line :r 1f. Y My invention consists in a metallic jointed coupling or strap to unite the lowerend-s of the harness haines, so that, {i1-st, it can be adjusted to suitthe'diinension of the collar, a'. e.,byl lengthening or shortening the strap; second, it can draw the ends oi the haines forcibly together and secure theu without relaxing; thirdyi't canbe loosened and detached without eiort; fourth, vit will holdwith perfect security, and be pernnanently attached to one part of the haines so that there will be no liability te lose'any ol'- the parte.

That others may understand my invention, I will particularly describe it.

A is the body or central part of my strap. Itis slitted lengthwise from I y one end nearly through 'its whole. length, and-the several holes a tra a are bored throughfrom side to side. t the slittecl end the part B ispiv oted permanently by a screw or rivet, and the part C is'secured by a pivot-pirror.screwinserted throughuone oi" l the holes a and passing through allug attached to C, which projects upwards into the slit in A. .The free ends ol' B and C are turned over so as to form hooks, which are to/ engage with the eyes utthe lower ends ,of the haines. -Thc hook D, at the free end of the part YC, is provided with asnap-spring, sol thatwhen this hook isv passed through the proper eye itcannot become disengaged without the application of force for that purpose.-

At the solid end of the part A is the projecting finger or st\ 1dE,Ahooki-ng downward at its end,q und to thc lower side of the part I?, directly over the stud E, when theparts A. andvB Vareslying in contaclnas shown in fig. I, is attached by a pivot-pin 'the stirrup F, by means of which the parts A and B are heldin contaetund the strap is made effective. y l

TheJ operation is very simple and efective. VWhen thelhames are adjusted upon the collar the strap is hanging to one part thereof by the snap-hook D. The hook Yat the frce'eudoi' the part B is then raised and inserted through the eye at the lower end of the other haine, bringing the strap to the position shown in lig. 3.

When this has been'donc the slitted end of A is raised up into the position shown by red lines in fig. 3; the' solid end of A is then raised in the opposite direction, bringing vthe parts into the position shown in iig. 1;.

n and when in that position the stirrup F is slippedv under the hook E,.and the parts are heldsecurely in that position, the elasticity ol' the collar being suilicient th maintain constant pressure upon the strrup, and thus.

prevent the accidental disengagement of hook and stirrup. It will be perceived that during the last movement of the part A it acts as a powerful lever, and with a smel'i expenditure of force will effect 4a powerful compression of the lower end of the collar so as to hold the llames securely in place, and `wlierrthe harness is to be removed a slight pressure upward will enable the attendant to release the stirrup E' from thehook and permit the strap to unfoldso that the part B inay be unhooked and-the' haines released. The part C may he piroted to theipart A at either of the several points a a by shifting the pivot-pin or screw so that the length of the strap may be adjusted totheeircumstanees and requirements of the'particular harness. A v l Havingldescribed my invention, what I claiur as new, and desire to secure by L etters'Iatent, is A jointed metallic' vhaine-strap, composed of thejg-'three' parts A, B, and C, constructed and .operating sub sltantially as set forth, and provided witha lloldingtleuice to lock'- and reta-in the 'parts in holding position.
